p Wilde? chamber or portion of the passageway at the bottom and the upper ends of the tubes communicate with the chamber or portion of the passageway at the top so that the heated water may circulate by gravity from the upper chamber through the tubes of the re ticulated structure, so as to dissipate "the heat, and from the tubes into the bottom chamber, and the upper chamber as a tubular extension '2, and a cap therefor as shown for filling the radiator with water or other cooling liquid.

The reticulated radiator structure, as previously stated, is composed of a series of fiat tubular elements arranged side to side or with their flat faces adjoining, and each of these tubular elements is composed of a pair of strips of metal 3 and 4, both of which in the present embodiment of my invention have similar transverse corrugations stamped therein and are slightly concave on the inner faces as at 5 and 6, respectively, so that when the strips are arranged in reverse relation, that is with the concave face of one facing the concave face of the other, the edges of the'two plates fit together so that they may be readily soldered or otherwise connected to provide a tight joint and form a flat zig-zag-tube as clearly shown in Figs. 2 and 5.

A plurality of these tubes are arranged side by'side but in reverse relation so that the tips of the corrugations or angular portions of the tube engage and fit against the tips ofsimilar corrugations or angular portions of the tube at each side thereof,

and it is an importantfeature of my invention that communicationis afforded-between the' adjoining tubes where the tips of the corrugations or angular walls thereof engage so that circulation is not only afforded from one end to end of these tubes, but at a plurality of points z intennediate the ends thereof with the'adjoining tubes, so that the water or cooling liquid may circulate laterally throu h the=reticulated radiator structure as wel as up and down therethrough.

ageat' this point;

To afford such communication the walls 3 of the tube at the tip of each corrugation are provided with'an elongated perforation 8,- extendin'g across 'thewidth of the flat tube, which registers with a corresponding opening similarly placed inthe wall 4, of the adjoining tube, and the contacting walls around theyopenings are soldered, welded or united in any other" suitable manner to provide a secure connection and prevent leak- It is to be particularly noted that this connection whereby communication is afforded between the adjoining tubes would be very difficult if not impossible to make satisfactorily after the flat tubes are completed, and the particular construction of of two adjoining tubes are provided with the elongated openings 7 and 8, therein, and laid together in reverse position so that the perforated corrugated wall of each strip faces inwardly and abuts against the tips of the corrugations of the other strip, with the perforations thereof registering with one another, and the abutting portions of these tWo strips are soldered, welded or otherwise joined together around the openings 7 and 8, to effect a tight joint; Obviously such connection can be easily made as the strips are entirely open at each side and permit convenient access to the" place where the connectionis to be made. All of the strips of which the radiator is to be constructed, with the possible exception of the outer strips, are assembled in pairs in this manner and thereafter the pairs are assembled so that the strip of one pair fits against a strip of another pair forming a flat tubular passageway therebetween and having the flanges at the edges thereof fitting together so that said strips may be readily soldered or other wise secured together at the edges without the necessity of making any connections at inaccessible places. Succeeding pairs of the previously assembled strips are added on in ike manner one after the other until the structure is built up tothe size'required for the particular radiator, after which the structure is fitted in the frame '1, and the ends of the tubes connected with the chambers of the shell with which they' areintended tocommunicate. 'The water,-er"cooling liquid may-then circulate through the flat tubes of which thereticulated struotureis composed not only lengthwise thereof but laterally between the tubular passa ways at a number-of points intermediate 0 the ends -thereofso that "thorough circulation is assured and cooling; ofthe: liquid rapidly "effected.
